  • Deriving information from an optically readable security element
    Patent number: 11562611
    Abstract: According to a first aspect of the invention, there is provided a method of deriving information from an optically readable security element, comprising: optically reading the optically readable security element, the optically readable security element comprising at least one optically readable structure, optically readable in response to excitation of the optically readable structure; the reading comprising determining data indicative of an optical property of the optically readable security element using first emission electromagnetic radiation, emitted in response to excitation of the optically readable structure; the deriving information further comprising using the determined data indicative of an optical property, in combination with a temporal excitation-emission relationship related to the optically readable structure, to derive the information.
    Type: Grant
    Filed: October 1, 2020
    Date of Patent: January 24, 2023
    Assignee: Quantum Base Limited

  • Optically deriving information from a security element
    Patent number: 11328193
    Abstract: According to a first aspect of the invention, there is provided a method of deriving information from an optically readable security element, the method comprising: optically reading the optically readable security element, the optically readable security element comprising one or more optically readable structures, optically readable in response to excitation of the one or more optically readable structures, the one or more optically readable structures being arranged to interact with one or more proximal structures of the optically readable security element, the interaction being such that an excitation-emission relationship for the one or more optically readable structures interacting with the one or more proximal structures, is different to an excitation-emission relationship for the one or more optically readable structures and the one or more proximal structures in isolation; the reading comprising: determining data indicative of an optical property of the optically readable security element using first
